Blooms of the non-toxic dinoflagellate Prorocentrum donghaiense are common in the East China Sea; however, the in situ impacts of these blooms on zooplankton community functions have not yet been conducted in this area. Using functional trait-based methods, we found that P. donghaiense bloom significantly changed the zooplankton community structure and functions in the coastal water of the East China Sea. Zooplankton species richness and biodiversity increased after the bloom. Based on body length, feeding type, trophic group and reproductive mode, we categorized zooplankton into four functional groups and characterized their dynamics. Before and after the bloom, the zooplankton community was dominated by herbivorous- and free-spawner- lineages represented by copepods and tunicates, while during the bloom, the zooplankton community was dominated by carnivorous- and egg-brooding- lineages represented by small jellyfish, chaetognaths and copepods.
无毒甲藻东海原甲藻的水华在东海很常见；然而，在该地区尚未进行这些水华对浮游动物群落功能的原位影响研究。本研究采用功能特征分析方法，发现东海原甲藻水华显著改变了东海近岸海域的浮游动物群落结构和功能。水华过后，浮游动物的物种丰富度和生物多样性增加。根据体长、摄食类型、营养级和生殖模式，我们将浮游动物分为四个功能群，并对其动态进行了描述。水华前后，浮游动物群落以桡足类和被囊动物为代表的草食性和自由生殖者类群为主，而在水华期间，以小型水母、箭虫和桡足类为代表的肉食性和卵胎生类群占主导地位。
